Jaky, there are women’s magazines like Yaldah (teen girls, anyways) that definitely show pictures of women/girls. If there are none for adult women, then why don’t you approach your favorite publisher to start one?
Besides, why would you specifically *want* to be seen in public? Especially if one is a woman? Your quote “So girl’s role is to work hard and somehow not be seen in public?” seems to harbor this misogynistic view that men allegedly have over women. Again, it is for your own dignity as a bas melech, not to put you in an undesirable role which it is not. If you don’t/can’t believe that, why don’t you (ask a Rav and also) write a Letter to the Editor asking why their policy is to not show pictures of women. Perhaps they can explain better.
Again, I see no loss in not showing a woman’s picture. I already mentioned that anyone, male or female, can take photos. And that you are free to publish a magazine or newspaper with pictures of women in it. And that, presumable, they would, too, in theory.
